| 摘 要： | 对等(peer-to-peer)网络的非集中结构、良好的自治性及容错性等特征,使其可能成为Internet上有效的信息共享模型.然而,内容定位问题仍然是大规模P2P网络中信息共享所面临的挑战.SemreX系统是一种P2P网络环境下的文献检索系统.针对SemreX系统,提出一种基于语义相似度的P2P拓扑管理和查询路由算法.仿真实验结果表明,语义拓扑能够有效地提高系统的搜索效率.

| Abstract: | The decentralized structure together with the self-organization and fault-tolerant features makes P2P network an effective model for information sharing, however, the content location remains a serious challenge of large scale P2P networks. In this paper, the SemreX is introduced, which is a P2P system for literature retrieval. Semantic-similarity-based P2P overlay and routing algorithms are proposed for SemreX. Experimental results show that searching in semantic overlay greatly improves the efficiency of search. |
